EPDM O-Rings & Seals

Ethylene-propylene is a copolymer of ethylene and propylene (EPM), or, in some cases, a terpolymer due to the addition of a diene monomer (EPDM). EPDM O-rings have great weathering resistance. A special characteristic of EPDM is its resistance to certain brake and hydraulic fluids (including Pydraul® and Fyrquel and Skydrol®).

EPDM O-rings and seals have a good resistance to steam. It needs to be taken into consideration that EPDM is not suitable with most hydrocarbons, such as oils, gasoline, kerosene and petroleum oils.

NewDealSeals supplies EPDM O-rings & seals in any dimension and in various compounds. Can we be of service with our expertise? Call +31(0)226362233 or mail us info@newdealseals.com.
